Ranunculus crassipes is a small flowering plant in the buttercup or crowfoot family Ranunculaceae that is native to the subantarctic region. The specific epithet comes from the Latin and refers to the plant's thicker and more succulent form compared to the closely related R. biternatus.
The plant is a perennial and stoloniferous herb, with glossy trifoliate leaves 15âÂÂ150 mm long and usually 3âÂÂ12 mm wide, with 2âÂÂ5 acutely toothed lobes. The flowers are solitary with 5âÂÂ7 petals and reddish-purple achenes. The plant flowers from December to March; it fruits in March, with the achenes persisting until September.
Ranunculus crassipes is found in boggy areas in the Kerguelen Islands, a French territory in the southern Indian Ocean, as well as on AustraliaâÂÂs Heard and Macquarie Islands.
